On this page you’ll find complete disassembly instructions for a HP Pavilion dv7.
This is my second guide for HP Pavilion dv7 series.
In this particular case I’m taking apart a HP Pavilion dv7-4177NR model.
I believe this guide should work for the all dv7-4000 series too.
READ THIS: I found that HP Pavilion dv7 come in different body types. If your laptop doesn’t look like one shown in this guide, check out my other guides. You’ll find links to other guide at the end of this post.
As you see I have a cracked screen. My target is replacing the damaged screen but I’ll do a few extra steps and show how to disassemble the entire laptop.
It’s not easy to replace the LCD on this HP laptop. In order to do so it’s necessary remove the palmrest assembly (STEPS 1-19), separate the display panel from the body (STEP 20-25) and only after that disassemble the display and replace the LCD (STEP 33-48).
Also, I show how to remove the motherboard and access the cooling fan (STEPS 26-32) but it’s not necessary to go though these steps in order to replace the LCD.
Make sure the computer is turned off.
Unlock and remove the battery.
Loosen five screws securing the bottom hatch.
Lift up and remove the hatch.
Under the bottom hatch you can access the following internal components:
– both memory modules ( I’ll leave them connected to the motherboard).
– wireless card.
– CMOS battery.
– hard drive.
HP Pavilion dv7 has a bay for the second hard drive but in my case I had only one hard drive installed.
Remove screws securing the hard drive assembly.
Unplug the hard drive cable from the motherboard.
Lift up and remove the hard drive assembly.
Remove one screw securing the DVD drive.
Pull the DVD drive to the left to disconnect it from the motherboard.
Remove the DVD drive.
Remove two screws securing the keyboard on the bottom.
Slide the keyboard release button to the left.
This button located in the battery compartment, on the left side from the battery connector.
After that you should be able to lift up the upper side of the keyboard.
Move the keyboard towards the display assembly so you can access the cable connector underneath.
In the following two steps I explain how to unlock the keyboard connector and release the cable.
Carefully lift up the left side of the connector retainer with your fingernail.
The retainer will open up at a 90 degree angle.
On this picture the connector is shown in the unlocked position.
Now you can pull the keyboard cable from the connector.
Remove the keyboard.
Remove all marked screws from the bottom.
UPDATE: Thanks to Just a Guy (comment 6):
On step 15 please see this image wait to remove screw with blue circle and SPECIALLY screw with yellow circle. Another note there are also screw ping circle to remove!
Remove yellow and blue ONLY on step 18 having laptop in SAME position of step 18 image. THIS IS IMPORTANT!!
So it why? Seeing step 24 image u can see that display hinges screw remaing are only 2! It leave it very weak and can damage screw plastic part near cooler.
Don’t forget to remove three screws in the DVD drive bay.
Remove two screws securing the palmrest assembly.
Disconnect the following cables:
– wireless card cable.
– touchpad cable.
– finger scanning device cable.
You unlock all three connectors using the same technique as for unlocking the keyboard connector.
Lift up the connector retainer.
Pull the cable from the connector.
Now you can start separating the palmrest assembly from the bottom cover.
You’ll have to wiggle the palmrest in order to unlock hidden latches.
Remove the palmrest assembly.
On the bottom side of the palmrest assembly you can access the following components:
– power button board.
– finger scanning device.
Now we are going to separate the display panel from the base.
First, we’ll release the wireless card antenna cables and then unplug the video cable.
Disconnect two antenna cables from the wireless card which is mounted on the bottom.
Unroute both wireless card antenna cables.
Unplug the video cable connector from the motherboard.
Remove two screws securing the display hinges.
Lift up and separate the display assembly from the base.
I will continue taking apart the display assembly and removing the screen in the step 33.
Laptop motherboard removal.
Remove two screws securing the motherboard.
Unplug the following cables (left to right):
– left speaker cable.
– USB board cable.
– right speaker cable.
Both speaker cables have a regular male-female connector type.
Unplug the male part from the female part. Do not pull by the wires.
Lift up the right side of the motherboard a little bit and unplug the DC jack cable from the motherboard.
Also, in order to remove the motherboard, it’s necessary to unplug the hard drive cable.
You’ll find this connector on the bottom side of the laptop close to the memory modules.
Start removing the motherboard from the bottom cover as it shown on the following picture.
Remove the motherboard.
The cooling fan assembly is mounted to the bottom side of the motherboard.
Yes, it’s necessary to remove the whole motherboard in order to remove and replace the fan.
The DC jack is mounted in the upper right corner of the base.
The DC jack harness can be easily removed after you remove one screw securing the DC jack bracket.
LCD screen removal and replacement instructions.
As I mentioned before, in order to replace the screen it’s necessary to separate the display panel from the base as it explained in steps 1-25.
You’ll find two screw covers located in the lower left and right corners of the display bezel.
Remove both covers with a sharp object.
Remove two screws found under those covers.
Start separating the bezel from the display back cover. I’m using the guitar pick for that (you can use a piece of plastic).
Insert the guitar pick between the bezel and display back cover and move along the side. This will help you to unlock the hidden latches.
Also, the bezel is glued to the screen with sticky tape. You’ll have to apply some reasonable force to separate the bezel.
Continue removing the bezel on the upper part of the display assembly.
Lift up and remove the right hinge cover.
Lift up and remove the left hinge cover.
Remove the screen bezel.
Remove eight screws securing the LCD assembly to the display back cover.
Disconnect the cable from the web camera module.
Now you can separate the LCD assembly from the display back cover.
Place the LCD face down on the table.
On the back side you can access the video cable and web camera cable. Both cables bundled into one harness.
Unglue the web camera cable from the back of the LCD.
Disconnect the video cable.
Remove the LCD assembly.
Remove two screws securing the right hinge mounting bracket. Transfer this bracket to the new screen.
Remove two more screws securing the left hinge mounting bracket. Transfer this bracket to the new screen.
Now you can replace the damaged/failed LCD and assemble everything back together following this guide in the reverse direction.
The best way to find a new replacement screen is searching by the model number.
The model number printed on the back side of the screen. In my case this is N173O6-L02 Rev. C.
When you search for a new LCD make sure the video connector on your new screen located in the same place as on the old screen.
